Aisa

Aisa or AISA may refer to:

Moirai

In Greek mythology, the Moirai or Moerae /ˈmɪrˌiː/ or /ˈmiːˌriː/ (Ancient Greek: Μοῖραι, "apportioners"), often known in English as the Fates (Latin: Fatae), were the white-robed incarnations of destiny; their Roman equivalent was the Parcae (euphemistically the "sparing ones"). Their number became fixed at three: Clotho (spinner), Lachesis (allotter) and Atropos (unturnable).

They controlled the mother thread of lifestyle of every mortal from birth to death. They were independent, at the helm of necessity, directed fate, and watched that the fate assigned to every being by eternal laws might take its course without obstruction. The gods and men had to submit to them, although Zeus's relationship with them is a matter of debate: some sources say he is the only one who can command them (the Zeus Moiragetes), yet others suggest he was also bound to the Moirai's dictates. In the Homeric poems Moira or Aisa, is related with the limit and end of life, and Zeus appears as the guider of destiny. In the Theogony of Hesiod, the three Moirai are personified, and are acting over the gods. Later they are daughters of Zeus and Themis, who was the embodiment of divine order and law. In Plato's Republic the Three Fates are daughters of Ananke (necessity).

Aeronáutica Industrial S.A.

Aeronáutica Industrial S.A. is a Spanish aeronautical company. The predecessor company, Talleres Loring had been founded by Jorge Loring in 1923.

History

The predecessor company was founded by Jorge Loring Martinez in Cuatro Vientos near Madrid in 1924.Aeronáutica Industrial S.A. was established in 1934 and through the course of the 20th century manufactured a number of light aircraft designs including Cierva autogyros.

In 1954, AISA purchased Spanish manufacturer Iberavia and took over the I-11 light plane project, eventually building around 400 examples. For a time it specialised in the maintenance and upgrading of helicopters. In 1982 it attempted, unsuccessfully, to market an autogyro design of its own, the GN.

The company was bought by CASA in 1995, but continues to operate under its own name.

Beta

Beta (UK /ˈbiːtə/ or US /ˈbeɪtə/; uppercase Β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα bḗta or Modern Greek: βήτα víta) is the second letter of the Greek alphabet. In Ancient Greek, beta represented the voiced bilabial plosive /b/. In Modern Greek, it represents the voiced labiodental fricative /v/. Letters that arose from beta include the Roman letter ⟨B⟩ and the Cyrillic letters ⟨Б⟩ and ⟨В⟩.

Name

Like the names of most other Greek letters, the name of beta was adopted from the acrophonic name of the corresponding letter in Phoenician, which was the common Semitic word *bayt ('house'). In Greek, the name was βῆτα bêta, pronounced [bɛ̂ːta] in Ancient Greek. It is spelled βήτα in modern monotonic orthography, and pronounced [ˈvita]. In US English, the name is pronounced /ˈbeɪtə/, while in British English it is pronounced /ˈbiːtə/.

History

The letter beta was derived from the Phoenician letter beth .

The letter Β had the largest number of highly divergent local forms. Besides the standard form (either rounded or pointed, ), there were forms as varied as (Gortyn), and (Thera), (Argos), (Melos), (Corinth), (Megara, Byzantium), (Cyclades).

Software release life cycle

A software release life cycle is the sum of the stages of development and maturity for a piece of computer software: ranging from its initial development to its eventual release, and including updated versions of the released version to help improve software or fix bugs still present in the software.

History

Usage of the "alpha/beta" test terminology originated at IBM. As long ago as the 1950s (and probably earlier), IBM used similar terminology for their hardware development. "A" test was the verification of a new product before public announcement. "B" test was the verification before releasing the product to be manufactured. "C" test was the final test before general availability of the product. As software became a significant part of IBM's offerings, the alpha test terminology was used to denote the pre-announcement test and beta test was used to show product readiness for general availability. Martin Belsky, a manager on some of IBM's earlier software projects claimed to have invented the terminology. IBM dropped the alpha/beta terminology during the 1960s, but by then it had received fairly wide notice. The usage of "beta test" to refer to testing done by customers was not done in IBM. Rather, IBM used the term "field test".

Beta (motorcycle manufacturer)

Beta is an Italian motorcycle manufacturer, specialising in off-road motorcycles. Beta are best known for their popular trials bikes. In 2005, they launched a range of enduro motorcycles using KTM engines. In 2010 they launched the new RR series, with a new engine made in-house. Beta motorcycles have been used by world trials champions such as Jordi Tarrés, Dougie Lampkin and Albert Cabestany.

History

Beta has its origins in 1904 as a bicycle manufacturing company named "Società Giuseppe Bianchi", originally based in Florence. The company started making motorcycles in 1948. The name Beta comes from the initials of Enzo Bianchi and Arrigo Tosi, who ran the company at that time. Focusing on two-stroke bikes through the 1950s and 1960s, the company started focusing development and production to off-road motorcycles in the 1970s.

Trials models

Beta have produced motorcycles for observed trials since the early 1980s and are now one of the leading manufacturers. Unlike the Trail and Enduro models, the trials bike have used Beta's own engines.
